NEMIX RAM DDR5 64GB 6400MHz CL52 1.1V 2Rx4 ECC Registered RDIMM 288-PIN Supermicro H14SHM memory upgrade

SKU CH-C5EY-EEFMH

64GB DDR5-6400 2Rx4 registered ECC RDIMM at 1.1V CL52, validated for Supermicro H14SHM motherboards

  • Total capacity64 GB
  • Rated speedDDR5 6400 (PC5 51200)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL52
  • Rated voltage1.1 V
  • Buffer typeRegistered
  • 64GB DDR5 capacity expands server memory headroom for demanding workloads
  • 6400MHz DDR5 speed with CL52 latency delivers rated performance without downclocking
  • 2Rx4 Registered ECC architecture corrects single-bit errors and stabilises fully populated slots
  • 1V operation matches the Supermicro H14SHM memory controller specification exactly
  • 288-pin RDIMM form factor fits the required motherboard slot type precisely

Exact-Match DDR5 Upgrade for Supermicro H14SHM

This 64 GB DDR5-6400 module is built to the precise rank, voltage and timing the Supermicro H14SHM motherboard expects. Registered ECC architecture ensures every slot runs fully populated at rated speed while correcting single-bit errors on the fly.

Thermals and Power at 1.10 V

Operating at 1.10 V, the RDIMM draws minimal power and produces low heat without a spreader. Registered buffering offloads the memory controller, keeping system thermals stable even when all slots are populated.

64 GB Capacity Per Module

Each stick delivers 64 GB in a 2Rx4 organisation, so total system memory scales with the number of slots your board supports. Builders needing smaller increments or non-ECC UDIMMs should look elsewhere.

Questions about this item

How do I install this 288-pin DDR5 RDIMM in my Supermicro H14SHM and which slot order does the manual require?

Power down, open the chassis, align the 288-pin key notch with the slot, press firmly until both latches click, then follow the motherboard manual's exact DIMM population sequence for registered ECC modules.

Will the ECC registered design or the Samsung Micron Hynix chips need any firmware updates or periodic replacement?

No firmware updates are required for the memory itself; ECC correction runs automatically, and the major OEM DRAM chips are rated for continuous server operation without scheduled replacement.

At 6400 MHz CL52 and 1.1 V, what thermal or power limit appears first when all slots stay fully populated under sustained load?

The registered buffer and 1.1 V operation keep per-module power low, so the platform's memory-controller thermal envelope is typically reached before any module-level limit.
